Luminaires with Class II LED modules and DALI dimmable: which issues do they raise ?

In recent months, customer demand for luminaires with Class II LED modules and with DALI dimmers has increased, something which Airfal’s technical department advises against due to the lack of guarantees for their correct use.

To understand better the situation, it is important to know what a Class II luminaire is.

Class II luminaires are characterised by additional safety measures such as double insulation or reinforced insulation. This type of insulation is mainly intended for manual electrical appliances, where extra insulation is required as they are used by people for many day-to-day activities.

Thanks to this double reinforcement, it is not necessary to use a ground connection when installing luminaires with Class II insulation. They do not depend on space conditions, which means a significant saving of time and, above all, of money when installing them.
However for some electrical appliances and installations it is recommended to use Class II insulation, such as lighting in the interior of a swimming pool. However, the use of Class II is not recommended for luminaires with LED modules and DALI dimming.

The elimination of the grounding of the installation can cause various electronic malfunctions and this implies several drawbacks and for that reason Airfal advises against this practice.
In the case of luminaires with LED modules, the reduction of Electromagnetic Interference (EMI) cannot be guaranteed by suppressing the earth connection, so it is not possible to comply with the relevant regulatory requirements. On the other hand, the grounding of LED luminaires ensures that the phenomenon of “LED GLOWING” or ghost lights does not occur. This phenomenon occurs when the luminaire with LED modules continues to emit a residual light when switched off or on standby. In the case of Class II luminaires, it is impossible to guarantee that there will be no “LED GLOWING”.

On the other hand, in the case of transients or voltage/current peaks in the power supply network, the presence of grounding causes the filters of the LED drivers to act by reducing or eliminating them. Without the presence of an earth ground connectionn (Class II), any transient will pass through the driver and reach the LEDs, shortening their life span or even destroying them.
We see in this graph a simple explanation, being the left part without grounding, and the right part with grounding:

On the right-hand side with earth connection the transient arrives much more damped than on the left-hand side without earth connection.
In the case of Class II DALI luminaires, it must be explained that DALI drivers are very sophisticated devices controlled by a small internal computer. The control and regulation of the LEDs is carried out under the supervision of a software integrated in the driver microprocessor.
For the correct operation of these devices, the computer that incorporates it needs to “measure” the reference potential 0. Without grounding, the measurement may be inaccurate, and the dimming may fail or have uncontrolled random effects (Current differences between luminaires, synchronism faults…). We can find cases of correct operation in which regulation problems may appear after some time.

In addition, the standard governing a DALI installation (IEC 62386) specifically specifies the need to have an earth connection to protect the control circuits and drivers, as shown in the following figures:

As stated at the beginning of the article, the lack of guarantees for quality, uninterrupted lighting is the main reason why the installation of Class II, LEDs and DALI dimming is not recommended.

Quality office lighting: 5 criteria to take into account

There can be no quality office lighting without a lighting project, as it will determine the photometric characteristics of the installation.

In particular, the average lighting level to be maintained depends on the use and people. For example, lighting levels for older people are not the same as the ones for younger people.
Quality office lighting will maintain its performance over time. Today, the evolution cycles of buildings and their uses are faster.

Lighting must therefore be able to meet the needs of these different developments. For example, a lighting system that can be upgraded – which can be used in English – will be able to be connected later, even if it was not connected when it was installed. In fact, quality lighting will be achieved through LED sources. T8 and even T5 fluorescent tubes are no longer relevant.

Modern lighting

Finally, quality lighting is also modern lighting. Thus, LED sources allow innovative product designs compared to historical sources. Through the lighting, it is the image of the company that is conveyed, because it fulfills a decorative function beyond the functional aspects.

Advantages of quality office lighting

1 – No visual discomfort

First of all, thanks to the absence of visual discomfort, quality office lighting will enable users to perform the tasks assigned to them in an efficient manner. It is thanks to an appropriate lighting level and limited glare that photometric performance will be achieved.

2 – Employee well-being

Secondly, because lighting can create a pleasant atmosphere in work areas, it will contribute to the well-being of employees.

3 – Appropriation of space

Personalisation of lighting will be part of the work space of staff. With little cost, modern, high-quality lighting allows workers to really take over the space, because they will be able to adapt the lighting service to their needs. Benefiting from an adapted and comfortable working environment, employees will be even more efficient.

4 – Positive image of the company

A positive image of the company is also one of the advantages of quality lighting. With LED and automatic management systems, the company will provide an updates image. For example, by controlling the presence in offices and daylight, it will give a modern look.

5 -Energy and maintenance savings

Finally, quality lighting saves energy and maintenance. These savings are a benefit that results from a well run lighting project. However, they should not be an objective in themselves.

Productivity of farms: LED lighting is more sustainable and economical

lighting farm housesAccording to Airfal, lighting plays a significant role in poultry and hog production, and has a huge impact on the performance of farms. Adequate lighting is necessary to ensure the health and growth of poultry and hogs, as the lighting needs vary according to the stages of the breeding. A well-designed, energy efficient lighting system can mean better brightness, better performance and lower energy costs.

Lighting in poultry farms

World farmers are facing a price war and must reduce their operating costs as much as possible. To meet this challenge, some farms will be forced to expand, as for example, dairy farms that will double their average size. This development implies an evolution in the technical equipment of the farms, especially the lights.

For that reason, LED lighting, which is modern and ecological, is presented as a solution that can be broken down according to the layout of each farm.

To illuminate a space as large as a building for livestock, significant savings are at stake. IN addition, maintain lighting facilities may be expansive. In this context, LED lighting, which does not require maintenance once installed, allows the farmer to focus on the day-to-day tasks inherent in his operation. Solidity is also an important criterion especially in poultry houses. The savings are measured very quickly in the short term with low power consumption.

Compared to a compact fluorescent lamp, a LED bulb has a very long life span, depending on the model, from 25,000 to 50,000 hours, ie between 6 and 12 years of use. It also has the quality not to heat and resist shocks while having high light yields with few watts consumed. Finally, the LED installations allow a variable lighting which turns out to be a real advantage in a hen house, for example, where you have to simulate a sunset.

Lighting for cattle farms

There is evidence that cattle are sensitive to light in buildings and the best results in milk production and fertility are achieved with a 16-hour light cycle of 150 to 180 lux followed by 8 hours of darkness. Indeed, the lengthening of the duration of days by means of stable lighting influences the production of melatonin, the sleep hormone. By prolonging the duration of daylight in winter, melatonin production is reduced and cows are more active.

With the Farm LED light fixture, Airfal intends to limit the consumption of electrical energy. Compared to current (sodium / halogen) and fluorescent (neon) lamps, Airfal light fixtures saves up to 75% in costs. Indeed, the lifetime of the Led lamps, established at 80,000 hours and the superior production of Lumens per Watt (130 lumens / Watt) allow a lower energy loss in the form of heat.

Lighting in underground mines

lighting underground minesA characteristic of underground mining operations is that, as we move from the surface to the interior, the darkness becomes more complete, which is why lighting is a very important and fundamental factor.

Under these conditions, it may be interesting for mining companies to focus on a key aspect of the production equipment, lighting.

In underground mines, it is vital to have safe and efficient lighting. Airfal manufactures high optical performance luminaires adapted to underground mines. These Atex certified light fixtures meet the highest safety standards and are explosion proof.

Explosion hazard in underground mines involves the use of special lighting to avoid possible accidents. In coal mines, firedamp concentration can be high, resulting in explosive atmospheres, An explosion can be caused by mechanical or electrical sparks.

Inside the mine, where the atmosphere is potentially explosive,  electricity has to be used safely. To prevent or minimize the effects of explosions, besides mine ventilation, electrical equipment and lighting has to be specially designed for use in explosive atmospheres.

All electrical equipment and lighting used in the mine must be able to withstand an internal explosion, and prevent any risk of spreading an explosion, which is called explosion-proof.

Lighting standards help ensure the safety of lighting installations in mines. The lighting systems used inside a mine must comply with the ATEX directive, and avoid any risk of explosion or propagation. The ATEX normative (explosive atmosphere) is the result of two European Directives (1994/9/EC and ATEX 137) for equipment intended for use in ATEX zones and 100A ATEX 1999/92/EC or safety of workers).

With many years of experience in technical lighting, Airfal has created the Minex luminaire which has been designed  for use in hazardous areas. With low maintenance cost, easy installation, and maximum security, the luminaire Minex is compliant with Atex. It was created especially for lighting in underground mines. It can also be used in other industrial facilities, both indoors or  outdoors.

Led light fixtures for the mining industry

Effective mining companies must use the latest technologies, including a safe and effective lighting system. The main characteristics of a lighting system for mines are safety, durability, efficiency and long life. Such elements are essential to survive in the harsh environment of the modern mining industry.

LED lighting is extremely popular today in the industry and in particular in mining, because of the many technical advantages of this technology. Increased longevity, efficiency, energy savings, respect for the environment are some of the many benefits that can offer LED light fixtures for mines. Airfal offers a range of lLED light fixtures suitable for mining, light and strong, with an exceptional lighting performance. These luminaires are designed for extreme environments, and can withstand explosions.

Led lighting for parking lots and car parks

Lighting in parking lots must be functional in order se as to meet with standardssafety. Motorized vehicles walk alongside pedestrians and cyclists in places that are often cramped and difficult to access. The diversity and quality of Airfal’s luminaires make it possible to create lighting that combine safety and luminous efficiency. Due to their long service life and very low power consumption, Airfal’s Led solutions reduce maintenance and energy costs, which represent a significant part of operating expenses for operators.

Choice of luminaires

Motor vehicles emit highly charged dust that is often conductive, and that affects electrical appliances. On the other hand, many modern parks are open to the outside, which brings direct or indirect projections of water on the luminaires.
It is therefore recommended to use waterproof luminaires with IP65 rating.
For luminaires placed in the lower part at low height, the use of grilles with anti-vandal screws is strongly recommended to avoid breakage during shocks with vehicles, or vandalism-related damage.

LED technology

Light Emitting Diodes (LEDs) generate and distribute light differently from HID luminaires. LEDs generate light via a semiconductor, unlike HID lamps, which produce light directly from electricity. In addition, they distribute light using multiple individual LEDs and optics, unlike a single bulb and reflectors inside the unit for HID lamps. Thanks to LED technology, the light is more evenly distributed over the planned surface, while consuming much less energy.

Energy costs

When it comes to energy savings, we need to look at the powers that are usually used for HID lighting compared to LED lighting. For a typical HID lamp, the average power is between 70 and 400 watts. If we look at the same range for a comparable LED light, the power is between 24 and 82 watts.
So, we can see that just by switching to LEDs, there will be a saving of 40% to 60% of energy consumption. From a cost point of view, switching to LEDs will save you about € 300 per device per year in electricity costs. Depending on the size of your facility, this can be a very important saving.
Reducing maintenance costs
In addition to the enormous cost savings associated with energy consumption, LEDs can also save you money by reducing maintenance costs. Due to the way in which LEDs generate light, their lifespan is maximum. Instead of stopping working properly after a while, the light output generated by the LEDs degrades very slowly over time.
As a result, the functional life (often greater than 100,000 hours) of a LED luminaire can be significantly longer than that of a HID lamp. For example, by replacing a conventional 250W HID luminaire with a LED fixture, a typical installation will generate significant savings in maintenance costs.

Lighting performance

Finally, although energy savings and savings in maintenance costs are important, it is imperative that lighting performance is not compromised. Here again, the performance of LEDs is far superior to other forms of lighting. Thanks to a multi-point design, LED lighting applications often provide a more evenly distributed light. This means that the light levels on a given surface will vary less between the mounting locations of the fixtures. HID luminaires, on the other hand, often produce a “point of light” directly below the luminaire, with light levels decreasing considerably as the distance between the luminaires increases.
In addition to a uniform distribution of light, LEDs are available in a range of CCT (Correlated Color Temperatures), and therefore offer a range of options to increase the visual perception of “light”.

What is a lux? How to measure the luminous flux per unit area?

Lux measures illuminance. Its symbol is “lx”.

Practical applications of lux

A Lux number indicates the luminous flux received per unit area. As an example, the human eye operates in a large amplitude of luminous flux:

  • Our full moon night vision is possible from 1 lx
  • During a very sunny summer day, our eyes are subjected to luminous flux of 130,000 lx
  • Our movements require a minimum of 5 lx to be secured
  • We read, write or work easily when the luminous flux is about 150 lx …

To understand this process, it is necessary to consider three concepts: illumination, light (lm) and lux (lx). The first is considered as the luminous flux that affects a certain area; In other words, how much light is coming from a light source on a surface?

To know the answer, we can imagine a lighting process in which a light source emits a certain amount of light; According to the international measurement system, the emitted light flux can be measured from lumens (lm). The higher the number of lm, the higher the illumination intensity provided by the source.

A Lux number indicates the luminous flux received per unit area.

When the light emitted reaches a specific area, the term lux (lx) is used. It is a unit of measurement equivalent to one lumen / m² and with which it is possible to calculate how much lighting affects a given area. However, in order to evaluate the amount of light, it is necessary to take into account aspects such as the dimensions of the space, the height of the luminaire and its distance to the target surface, as well as the photometric data of the lamps and their amount.

It should be noted that if the light source is close to the target area, there will be more lux, but if it is far, there will be less. For example, a luminaire emits two thousand lumens on a surface of one square meter, in this way one will have two thousand lux emitted on this zone, which represents a lot of light. On the other hand, if the same amount of light is used on an area of ​​20 square meters, the illumination of this spot is only 200 lux, ie less light.

To reach a luminous equilibrium, one will be able to use means, techniques and software to calculate it. In addition, the aesthetic and functional aspects should be considered according to the use of each area to be illuminated. The use of luxmeters makes it possible to obtain an optimal level of illumination.
